4.2.4 Intake and vent pipe length
The maximum allowed length of pipes depends on the flow resistance of each part installed to go from the equipment up to the intake
and vent points.
Overall flow resistance, calculated according to tables 4 and 5, must not exceed the “Maximum allowed length”. The calculation must
consider both vent and intake ducts and should change based on the diameter of the pipes used (35 mm or 60 mm).
